Which company ends the month on top by market cap? The monthly books are the fastest-moving read on mega-cap rotation, and for August 2026 the live monthly ladder sits on Manifold—Polymarket has not relisted a monthly, leaving its end-of-December 2026 Categorical (the deepest book in this stack) as the durable cross-exchange leg.

The stack pairs the near-term monthly against the year-end durable, then adds the 2nd- and 3rd-place books, where most of the actual rotation shows up—the top slot changes hands far less often than the places behind it.

Anchor: Manifold largest-company-end-of-august-2026, settling September 1, 2026.

August's monthly Categorical on Manifold next to Polymarket's end-of-December durable. When the two disagree on the leader, the market is pricing a handoff somewhere in the back half of the year.

Second and third place for August. These books carry the rotation signal—the leader is usually stable month to month, so a shift in the 2nd/3rd distribution is the earlier tell that the ordering at the top is under pressure.

Daily history on the August monthly book. Mid-month is when the distribution is most informative—early in a month the book is still anchored to the prior month's result, and by the last week it has usually converged.

  • Monthly vs. year-end split. The Manifold August book and the Polymarket December book price the same question at different horizons. A divergence between them is the cleanest read on whether the market expects the current leader to hold through 2026.
  • Watch 2nd and 3rd, not 1st. The top slot rarely turns over inside a single month. Movement in the 2nd- and 3rd-place distributions is the leading indicator for the top-line book.
  • Cross-exchange coverage is asymmetric right now. Polymarket carries the depth on the year-end question; Manifold carries the monthly cadence. The custodian re-pairs a Polymarket monthly onto the anchor row automatically if one relists.
  • Earnings as the repricing trigger. Mega-cap earnings weeks are when these books move most—a beat that shifts a market cap by a few percent can flip a monthly ordering outright.
